Chain of Evidence framework enables pixel-level visual attribution for retrieval-augmented generation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called Chain of Evidence (CoE) to improve iterative retrieval-augmented generation (iRAG) systems. CoE utilizes Vision-Language Models to directly analyze screenshots of retrieved documents, enabling precise pixel-level attribution and overcoming the limitations of text-only parsing. This approach aims to enhance reasoning over visually rich documents like presentation slides and charts, preserving spatial logic and layout cues. AI

IMPACT This framework could enhance AI's ability to reason over complex visual documents, improving accuracy in tasks requiring layout and spatial understanding.

    Chain of Evidence: Pixel-Level Visual Attribution for Iterative Retrieval-Augmented Generation

    arXiv:2605.01284v1 Announce Type: new Abstract: Iterative Retrieval-Augmented Generation (iRAG) has emerged as a powerful paradigm for answering complex multi-hop questions by progressively retrieving and reasoning over external documents. However, current systems predominantly o…
